Question

measurements of two electric currents are shown in the chart. which best compares the two currents? electric currents current volts amperes x 1.5 7.8 y 9 0.5 current x has a greater potential difference, and the charges flow at a slower rate. current y has a greater potential difference, and the charges flow at a slower rate. current x has a greater potential difference, and the charges flow at a faster rate. current y has a greater potential difference, and the charges flow at a faster rate.

Explanation:

Step1: Recall potential - difference and current concepts

Potential difference is measured in volts and current (rate of charge - flow) is measured in amperes.

Step2: Compare potential differences

Current X has 15 volts and current Y has 9 volts. So, current X has a greater potential difference.

Step3: Compare rates of charge - flow

Current X has 7.8 amperes and current Y has 0.5 amperes. So, charges in current X flow at a faster rate.

Answer:

Current X has a greater potential difference, and the charges flow at a faster rate.
